Abstract: A smoke detector is disclosed containing a radiation source and a radiation receiver arranged externally of a direct radiation region of the radiation source. In the presence of smoke or other combustion particles in the radiation region the radiation receiver is impinged by scattered radiation. The smoke detector contains optical elements which can be altered by external mechanical actuation, by means of which it is possible to alter in a predetermined manner an output signal of the radiation receiver. In this regard it is possible to either mechanically alter the solid angle which is so-to-speak viewed by the radiation receiver or the solid angle irradiated by the radiation source. The constriction of the active solid angle is preferably accomplished by a diaphragm or membrane displaceable along the radiation direction. Displacement of the diagram is preferably achieved in that, this diaphragm engages by means of dogs or detents in a cam groove, such as a helical-shaped groove of a cam disk, and by rotating the cam disk there can be achieved a defined displacement of the diaphragm.

Title: Distributed receiver system for antenna array
Inventor: BODONYI JANOS
IPC: H01Q3/26
Filed: 1990-09-10
Granted: 2000-01-11
Abstract: In an antenna array of large dimensions, such as might be used for high frequency radar, the antennas 1a, lb, will be connected by short feeders 2a, 2b, to receivers 3a, 3b, which will consequently be distributed over a considerable distance. To calibrate such an antenna array to compensate for variations in the transfer functions of the receivers will necessitate the same test signal being fed into each element in turn to measure the receiver output, and this could be time consuming and hence reduce the time available for use of the array.        To overcome this disadvantage, a loop 5 is connected at various toppings to the feeders 2a, 2b, the respective antennas being disconnected, and sinusoidal tones are injected into the left hand and right hand ends of the loop. The outputs of the receivers are measured, and provides a measure of the transfer functions of the receivers and hence enables discrepancies between them to be corrected;

Title: Adjustable screed and adjustment means therefor
Inventor: HAID RAYMOND F
IPC: E01C19/00
Filed: 1991-09-18
Granted: 1995-12-12
Abstract: A power screed for smoothing freshly poured concrete and a method of operating the screed is described.  The screed has adjustable vertical support means to account for uneveness in the supporting surface.  The support means are located near each side of the screed and are controlled by hydraulic motors. The screed can be adjusted manually and/or automatically through the use of an external laser source.  When concrete is poured, it is roughly smoothed by rakes or similar tools.  The screed is then advanced over the concrete with the lowest level of the screed determining the level of the surface of the concrete.  Where the supporting surface upon which the concrete is poured is uneven, the screed can be raised or lowered to ensure that the upper surface of the concrete is level.  The support means are each composed of two screw jacks mounted on a ski.  As the screed advances through the concrete, the support means leaves a track in the concrete which must be smoothed and filled manually.  Presently, the level of a screed is controlled by bulkheads located at either side of the screed.  The bulkheads must be installed in such a manner that an upper level of th bulkheads corresponds to an upper level of the finished concrete.  With the present invention, the bulkheads can be eliminated.

Granted: 1997-12-02
Abstract: A door operation control system has a door opening for moving a door between open and closed positions.   A door operator control circuit selectively operates the drive means to move the door between the open and closed positions.  An obstruction detection device detects whether there  is an obstruction in the path of the door between the open and closed positions and generates a signal in response thereto. The obstruction detection device is connected to the control circuit by wiring to permit operation of the door opener in the absence of a signal from the obstruction detection device and to prevent certain operations of the door opener in the presence of a signal from the obstruction detection device. An error detection circuit detects faults or errors in the wiring and generates a signal to prevent certain operations of the door operator when the faults or errors are detected. The error detection circuit prevents unsafe operation of the door opener if a wiring error has made the obstruction detection device inoperative.

Title: Perfected roller-skating doll
Inventor: LLORENS D JAIME FERRI
IPC: A63H11/18
Filed: 1992-04-08
Granted: 1996-12-17
Abstract: This invention refers to perfected roller-skating doll of the type that alternately moves its legs and head in time, and which has two speeds that alternate while the doll is in operation. The system is based on a gear mechanism worked by a motor, the said mechanism including features that allow the axial movement of a cog wheel so that the latter can engage alternately with one or another pinion, of different sizes, in order to achieve the two speeds. The mechanism is complemented with a drum which is made to revolve in order to transmit movement to the legs. The drum in question is provided with a winding, ring-shaped groove inside which a pin emerging from the respective leg freely moves. This pin is the means whereby the leg is joined to the mechanism assembly and, in particular, to the drum groove. On the shaft on which the drum-affecting pinion is mounted, there is a socket integral with the said pinion and which houses a widened section of the aforementioned shaft. On this widened section is situated a torus with respect to which the shaft can freely slide, in such a way that the revolution of the latter is not transmitted to the drum, thereby constituting a clutch assembly that comes into operation at certain times when it is desired that the motor should work at an idling speed.
